Unfortunately, adding 3rd party packages is still somewhat
non-trivial.  The problem is that although the setup.py files do
properly reference all dependencies for a given package, the
configure.zcml files for those packages typically do not include their
zcml dependencies.  I consider this a bug and would really like to fix
it at some point.  In the mean time though, if you want to play with
z3c.formdemo, you should just set it up as a stand alone application
rather than adding it to another package as a dependency.  See the
pypi page for instructions on how to do this:
http://pypi.python.org/pypi/z3c.formdemo/.  Since it's only five
lines, I'll just paste it into this email:

$ svn co svn://svn.zope.org/repos/main/z3c.formdemo/trunk formdemo
$ cd formdemo
$ python bootstrap.py
$ ./bin/buildout
$ ./bin/demo fg

Hope that helps!
